Diff funktion works wrong opentx

Hy,
opentx v2.012 and all older

Diff Funktion at mixer or input works wrong.

Example1:
Mixer
source: Ail
weight: 100%
offset: 0%
trim 0%
Diff: 50%
here the Diff funktion works correct , but only here!
with offset 0% and trim 0%

Example2:
Mixer
Source: Ail
weight: 20%
offset: 50%
trim 0%
Diff: 50%
there will be no Diff because there is no neg value

Test it!

less weight and much offset you need often at gliders with ail and spoiler funktion
and you need the Diff in correct way!

same effet with much trim, no or wrong Diff-funktion
-----------------

instead of Diff funktion you can use a 3 point-curve with 50% at negativ and 100% at positiv
this will work correct like the diff funktion should

-------------------

think Diff calculation is at the wrong place
must be at the same place and same funktion as a 3-point curve

-----------------

positiv Diff value reduces the lower, neg side, thats ok ( -50% +30%Diff) = -20%
negativ Diff value should increase the neg side, ( -50% -30%Diff) = -80%
but it decrese the pos side, thats wrong

the correct diff-funktion has to work only at the neg side, never at the pos side
